This commit improves expense flow management through a better integration
of activities and addition of automated activities. Several things are done
in this commit :
* expense sheet (report) model do not inherit from mail.activity.mixin.
This commit adds the inherit so that expense users and managers can now
schedule and manage activities on expense reports. This will help them
in their daily job;
* automatic activities generation is added for expense reports. Activities
are generated for approval. They are also automatically set as done when
validating or unlinked when refusing or resetting to avoid bloating users
with unnecessary activities;
* a menu to configure activity types is added. Indeed HR managers should be
able to see and configure activity types related to their job;
* filters are added to be able to use the systray and to filter the kanban
view based on activities
Having automated activities allow to replace some messages and tracking
that were implemented to warn people of expense reports to approve.
This commit therefore
* simplifies the tracking as tracking to confirm reports is not necessary
anymore;
* removes to approve subtype on report model as well as its parent subtype
on the department. This allows to simplify chatter in hr_expense app;
